Well, this looks like bogus -- you connect to nonexistent
signals using several years deprecated API and then attach
errors revealing other problems in your code, as first one
(at least) is completely unrelated.

What are you trying to achieve?  Don't you want to connect
to signals of some widgets on that page instead?  Have you
read the tutorial (http://www.gtk.org/tutorial/), namely the
part about signals?
